Abstract

A display substrate includes sub-pixels on a base substrate and each including a sub-pixel aperture area, a reflective layer, an insulating layer, independent anode patterns, a light-emitting function layer and a cathode. An orthographic projection of the reflective layer onto the base substrate at least partially overlaps an orthographic projection of the sub-pixel aperture area onto the base substrate. Each of orthographic projections of the anode patterns onto the base substrate at least partially overlaps the orthographic projection of the sub-pixel aperture area onto the base substrate. An orthographic projection of the light-emitting function layer onto the base substrate is within the orthographic projection of the sub-pixel aperture area onto the base substrate. An orthographic projection of the cathode onto the base substrate covers the orthographic projection of the light-emitting function layer onto the base substrate.
